Abstract

A process for cleaning and disinfecting contact lenses with a single solution is described. The process utilizes the cleaning effect of a cleaning agent in combination with the solvent action of water and physical agitation of the lens (i.e. by means of rubbing). The cleaning agent is selected from polycarboxylates. The preferred cleaning agent is citrate. The need to utilize additional products to clean the lenses is eliminated.
